DSDPlus Help Decoding a Digital Channel Using DSD+

[krizzle1]

Hello,

I'm trying to decode and listen to a local emergency service frequency in my area. I'm using Airspy, Virtual Audio Cable, and DSD+ to try and decode this station a well as find the talk group and time slot so I can program it into my DMR. Here's the info on the station and you can see it's missing the TG and SL. I have Airspy running tuned to the station and DSD+ open. I hear the garbled digital audio and DSD+ seems to be registering as I see movement on the audio screen, but get no information on the event log. Do my settings look appropriate? I can't seem to figure out why I can't decode this frequency. I figured this was a standard DMR channel but could this be something that DSD+ cannot decode? Any help is appreciated.


Screenshots of the applications and freq below:

I don't see any indication of voice traffic in the terminal window.

In the radio reference description for this channel it says it's EMS dispatch, so I figured it would be a voice channel. What would voice traffic look like in the terminal? This is only a short snip of the long info that was returned in the terminal window.

Here's what a conventional DMR voice call looks like feeding DSD+ with FMP24:





Maybe try using FMPA instead of SDR#.

That license, WQME843 expired 4 years ago. They have another license WRPG215 which also lists 464.7500. Try that freq also.

I agree that FMPA would be the way to go.

This. Light green at bottom is an active transmission. Darker green is what's been logged. Welcome to the RR forums

Thanks for the information everyone. Are there any solid docs on FMPA? Do I need DSD+ Fastlane for it?

When you downloaded the public version, did you download the FMPA files?



In any event, the public version is quite old and lacks many features found in FastLane. FastLane does not need virtual or vb cables either.

Member @CanesFan95 just put this together.

I do have FMPA but when I try and open it, it opens a terminal window with some info but promptly closes. I'll check out DSD+ Fastlane.
I should have specified a bit more. My goal with this is to really find the TG and slot so I can program this frequency into my cheap DMR handheld. Hopefully it's possible.

Thanks.

You can't run FMP* by just double clicking on it in File Explorer. You need to go into Console and give FMP valid startup parameters.

^ You can on the current Fast Lane version. The gain will be skyhigh and you'll get a nasty loud noise floor sound. (I wish they would lower the default gains which are way too high and tune to something other than 99.9 MHz of all things.)

You can in the public version also. Suitable for analog.

Gain and freq would be set with an appropriate bat file.

What frequency and gain would work for everybody? If the gain was low, people would complain they can't receive anything.

So set up batch files that have the settings you want. Make a dozen batch files, one for each parameter you want changed. You set the files the way you want things to start, you don't HAVE to use the default batch files.

The solution is to use the software as designed. Gain can be adjusted during operation with G/g.
